Title: Rotary Machines
IPC: B41F13/08
Filed: 1966-10-11
Abstract: 1,162,708. Rotary printing machines. HARRIS-INTERTYPE CORP. 11 Oct., 1966 [20 Oct., 1965 (2)], No. 45399/66. Heading B6C. Rotary machines having co-operating cylinders with gaps in their peripheries are provided with means adjacent to a gap of at least one of the cylinders for causing the pressure between the cylinders to change over an appreciable angular movement of the cylinder, when the gap is in the vicinity of the point of contact of the cylinders. In particular, the invention applies to the blanket cylinder of a rotary press where means for attaching a blanket is provided in a gap in the surface of the cylinder, but it is also applicable for plate and impression cylinders where means are provided for attaching printing plates and sheets of paper in respective gaps in the surfaces of the cylinders (Fig. 1, not shown). Fig. 2 illustrates a blanket cylinder 11 with a gap in its surface and means for fixing the blanket to the cylinder. The leading and trailing sides 75, 70 of the gap are provided with undercuts 27, 32 which extend in the direction of the circumference of the cylinder undercutting the periphery and hence forming resilient cantilevered projections 29, 33, the deflection being limited by stops 34, held in position by screws 35. The undercut may be filled with a resilient material which deforms but limits movement of the cantilevered projection (Fig. 3, not shown). Alternatively an alloy steel insert is positioned adjacent the gap (Fig. 4), an undercut 50 being formed in the insert and a wedge block 51 being supported on an inclined surface 50a; the block 51 can be moved up and down the inclined surface by rotation of adjusting screws 55, thus moving the top of the wedge block 51a towards and away from the cantilever projection 53. A third embodiment involves a cut-out portion adjacent the gap, the cut-out being completely filled by a resiliently deflectable wedge (Fig. 5, not shown). Blanket gripping device (Fig. 2).-The ends of the blanket carry bars 60a and 60b which cooperate with clamps 18a, 18b in a dovetail fashion. Clamp member 18a contains a rotatable shaft 64 which is turned counterclockwise to tighten the blanket about the cylinder. Clamp member 18b includes a fixed support 66 and a movable support 67 which slides on support 66 by means of adjustment screws 71 abutting rod 72 which in turn abuts the side of the gap. On tightening the screw, the blanket is tensioned, preventing angular misalignment on the cylinder.

Abstract: 1,024,328. Boundary layer control. GENERAL ELECTRIC CO. Dec. 3, 1962 [Dec. 5, 1961], No. 45488/62. Heading F2R. A body having a fluid stream flowing thereover comprises a upstream portion, and a downstream portion connected by a transition surface portion, said surface portions not being co-planar, and the upstream and downstream portions being offset and parallel, the body before formed such that the static pressure adjacent the downstream portion is greater than the pressure at the upstream portion, and a bleed duct in the transition surface to remove a predetermined amount of fluid flowing over the transition surface. The apparatus (in Fig. 2, not shown) is constructed as a diffuser having non-planar straight walls 10, 12 symmetrical about axis and radially separated by a transition surface to provide a stepped portion AB below which is formed a duct 15 through which boundary flow is drawn by a pump 16 and re-directed to the main flow by a nozzle 17. It is stated that the main undisturbed flow follows streamlines as shown at 13 whereas the flow contained by dividing streamline 14 is drawn into duct 15. The portion of the wall from 10 to 15 is designed as a constant velocity wall and has a constant pressure along the wall so that the boundary layer does not separate. By keeping the limit of the free stream away from the wall as indicated by streamline 13, diffusion is undisturbed by the boundary layer. The pump 16 may be dispensed with, the transition surface being extended into a closed circuit having a self-pumping action (Fig. 4, not shown).

Abstract: 1,203,414. Doffing comb for carding engine. DEUTSCHER SPINNEREIMASCHINENBAU INGOLSTADT NIEDERLASSUNG DER SCHUBERT & SALZER MASCHINENTABRIK A.G. 5 Oct., 1967 [25 Oct., 1966], No. 47822/66. Heading D1N. To overcome or at least diminish undesired vibrations, a doffer comb device consists of an oscillatory two-or-more mass system of which an end mass is a carrier of the doffer comb and together with a spring member, which connects this end mass with an adjacent mass which may be an excitation mass, forms an oscillation compensator whose natural frequency is tuned to the excitation frequency of the excitation mass. When the excitation frequency coincides with the natural frequency of the oscillation compensator, the excitation mass becomes non-oscillating and the compensator mass carries out an oscillation superimposed on the basic swing. The doffer comb may carry out linear or arcuate oscillations. The excitation may be produced through mechanical, electromagnetic or hydraulic means. In Figure 4, the comb carrier 1, the cross pieces 2 and the comb 3 together represent the compensating mass, and the torsion rod 4 represents the spring member. The excitation mass consists of the reinforced end 5 of bar 4, torque tube 6, clamping ring 7, fly wheel 8, rotating shaft 9, bracket 10, roller bearings 11 and 12, coupling 13, crankshaft 14, balance weights 15 and 16 and fly wheel with pulley 8. By means of motor 22 the tube 6 and thus the entire device maintains a periodic basic swing, the periodically altering inertia forces of the drive acting as excitation forces on the excitation mass. The doffer device may carry a sensing element (e.g. an electromagnetic pick up) sensing the compensating mass oscillations, whereby the compensating frequency sensed serves through an amplifier as an excitation frequency to the drive. To prevent an undesired resonance point being passed through on starting and stopping the device, a supplementary oscillatory mass can be directly coupled with the excitation mass through a spring member, the excitation mass being adjacent to the compensating mass.
